Conception is defined as the inception of pregnancy or the exact moment when an egg is fertilized. Logically, it seems like your conception date and intercourse date would be the same. That may be the case, but since sperm can live inside a woman's body for up to three days, conception can happen three days after intercourse, depending on when you ovulate. If you have been charting your ovulation date, you may be able to estimate when conception occurred. If you have a regular 28-day cycle, conception usually occurs about two weeks after the first day of your last period.
